Does this mean you know someone at Behringer?
Any chance of pleading for some information?

You loose
I opened my BCR up and it has an OKI L671000 MPU in it.
It's a 32bit RISC controller with a built in UART controller.
Oki's info page on the micro controller
It uses 1M DRAM chip 4C1M16C3D
Link to DRAM datasheet
There is a 32pin chip in an ic socket that is glued in (as is Behringer's excellent policy)
This is marked "BCR2000 Ver1.04"
Removing this label reveals that it is a 39SF040 (Flash memory 512k x 8bit)
You can get the datasheet here
All we need now is for someone to whip out the chip and read the data. (I don't have anything that will read this flash.)
All the best
